Indicators not working

[philipbrown123]

My hazards work but not the indicators. The AA who were out to sort another problem said it is not the relay, control unit or a fuse so must be the stalk / switch.
Has anyone here had a similar problem ? The car is a 1999 speed six cerb.

The switches used are similar to this one ...

... and there are 2 (one for left, one for right) and are reasonably easy to access and it'll be obvious if a lever is broken off the switch.

The set-up on the Cerbera means that a different switch does each side so it's seems strange that both sides should fail together though.

I'd suspect it's unlikely to be the switches.

If you push the indicator stalk up / down while the car is off you should be able to hear a very defnite click when the stalk pushes the microswitch.

If you hear this click both ways it's probably not a switch and is more likely to be a damaged wire / connection going between the box and the switch.

If you take a look under your dashboard you should see something like this:


Just ignore the red arrow.

Not much help but my indicators stopped working for no reason I could find (the wipers were also affected) and later cured themselves so if you find the cause I'd be interested

I've had to replace the steering wheel ECU once. It is tucked up around the steering column hidden by the leather covered panels. If you have a fellow Cerb owner near by you can test by swapping the unit over temporarily.

I get that too, just very infrequently so I often forget about it. I found hitting the hazards "reset" the indicators and everything starts to work again as usual.

One day i'll get round to not resetting them and actually get the meter on the cables to see what's going on.

Thanks for the info. I am using the hazards anyway when indicating is 'critical' so this is not resetting them.

The screws securing the micro switches fell out on mine, only took 20 mins to fix, although the wheel and cover has to come off if it is that.

I take it your wipers are working then?

[philipbrown123]

Wipers are working.

I'm not an expert , but also check the flat cable that runs from the back of the steering wheel. I lost wipers and the cable had been creased and caused an intermittent break.

The pic below is not the exact cable but it looks like it!

That flat ribbon cable only does the functions on the steering wheel itself, not the indicators
